Product details

Overview

IKQ100N120CH7XKSA1 from Infineon is a 1200 V, 100 A high-speed TRENCHSTOP™ IGBT 7 co-packed with a full-rated 100 A ultra-fast recovery emitter-controlled diode in a PG-TO247-3-PLUS package. It delivers V_CE(sat) = 1.7 V at 25°C, t_r = 59 ns, and Q_rr = 3.08 µC, enabling high-efficiency hard-switching in 3-level NPC/T-type inverters for industrial UPS and EV-charging systems.

For engineers reviewing the IKQ100N120CH7XKSA1 datasheet, IKQ100N120CH7XKSA1 pinout, IKQ100N120CH7XKSA1 application, or IKQ100N120CH7XKSA1 equivalent, key selection criteria include its positive V_CE(sat) temperature coefficient for stable paralleling, soft-commutating diode behavior, 175°C max junction rating, and low E_off (2.52 mJ) at 25°C for high-frequency operation.

Technical Context

This device integrates an IGBT and a matched rapid diode in a single TO247-3-PLUS package, sharing thermal and electrical interfaces to minimize parasitic inductance (L_E = 13 nH). Its gate charge (Q_G = 696 nC) and low C_res/C_ies ratio support fast, controllable switching with reduced voltage overshoot.

The IGBT uses TRENCHSTOP™ 7 cell architecture for optimized conduction–switching trade-off, while the diode features emitter control for soft reverse recovery (trr = 148 ns at 25°C, Irrm = 39 A) and low Q_rr. Both elements are qualified per JEDEC47/20/22 for industrial reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200 V - supports DC-link voltages up to 960 V in 3L-NPC topologies with margin.
I_C / I_F	100 A continuous - rated for both IGBT collector and diode forward current at T_c = 100°C.
V_CE(sat)	1.7 V @ 100 A, 25°C - enables low conduction loss in high-power inverters.
t_r / t_f	59 ns / 30 ns @ 100 A - supports >20 kHz hard-switching with minimal dead-time requirements.
Q_rr	3.08 µC @ 25°C - reduces diode-induced turn-on loss and EMI in bridge-leg commutation.
R_th(j-c) (IGBT)	0.16–0.21 K/W - allows direct heatsink mounting with predictable thermal resistance for thermal design.
T_vj(max)	175°C - extends safe operating area under overload and transient conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT+diode module applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW100N120CS7	Same 1200 V/100 A rating but in TO247-4L package with Kelvin emitter; lower V_CE(sat) (1.65 V) and Q_G (620 nC); no integrated diode.	Requires external diode; better suited for ultra-high-frequency (>30 kHz) servo drives where gate drive precision outweighs integration benefit.	Select when gate drive loop inductance must be minimized and discrete diode optimization is acceptable.
FF100R12ME4	1200 V/100 A EconoDUAL™ 2-module; includes NTC, press-fit terminals, and dual IGBT/diode pairs; higher R_th(j-c) (0.25 K/W).	Targeted at 3-phase motor drives with integrated baseplate cooling; not pin-compatible; requires PCB redesign.	Select for scalable multi-kW systems needing built-in thermal monitoring and standardized busbar interface.

Compared with IKW100N120CS7 and FF100R12ME4, IKQ100N120CH7XKSA1 uniquely balances integrated diode functionality, TO247-3 simplicity, and soft-recovery performance-making it optimal for cost-sensitive, space-constrained 3L inverter designs where board-level integration and EMI control are critical.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

The datasheet specifies RG(off) ≥ 4 Ω for SOA compliance. For 100 A operation at 175°C, a 7 Ω gate resistor achieves td(off) = 607 ns and E_off = 4.52 mJ-balancing speed and voltage overshoot. Values above 12 Ω increase switching losses disproportionately without meaningful dv/dt reduction.

Does this device require a negative gate voltage for turn-off?

No. The device is fully specified for V_GE = 0 V turn-off and exhibits stable blocking at V_CE = 1200 V with zero gate bias. A −5 V to −8 V negative bias may improve noise immunity in high-dv/dt environments but is not required for functional operation per JEDEC qualification.

Can IKQ100N120CH7XKSA1 be paralleled without external emitter resistors?

Yes. Its positive V_CE(sat) temperature coefficient ensures inherent current balancing across parallel units. Testing confirms <5% current imbalance at 100 A per device with matched gate drive and thermal mounting-no emitter resistors needed for up to four devices in parallel.

Is the integrated diode rated for continuous 100 A conduction?

Yes. The diode is rated for I_F = 100 A continuous at T_c = 88°C (Table 4), matching the IGBT's I_C rating. Its VF = 2.5–3.0 V and low Q_rr ensure low forward loss and minimal reverse recovery stress in bidirectional switching applications.
